PROCESS FOR'MAKING PARTS FOR OPHTHALMIC MOUNTINGS.

Original application filed February 23, 1922, Serial No. 538,635. Divided and this application filed May 26, 1923. Serial No. 641,583.

To all whom it may concern:

Be it known that we, ELMER L. SoHU- MACHER and WILLIAM H. BOUTELLE, citizens of the United States, residing at Southbridge and Sturbridge, respectively, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Processes for Making Parts for Ophthalmic Mountings, of which the following is a specification.

This invention relates to improvements in parts for ophthalmic mountings, and has particular reference to new methods of producing combination mountings formed from a combination of metallic and non-metallic parts. One of the principal objects of the present invention is the provision of a novel-process by the use of which it will be possibleto form temples or other parts for ophthalmic mountings having a metal core enclosed by non-metallic material in which said non-metallic covering for the temple may be formed from the same" stock as the front or lens receiving portion of the mounting, so that the parts will exactlymatcli in color, marking, and the like.

A further object of the invention is the provision of a novel process of producing parts of such improved completed construction, which will better retaln their shapes and stand up more satisfactorily under service conditions than structures produced by hitherto known processes.

Other objects and advantages of the improved process should be readily apparent by reference to the following description taken in connection with the accompanying drawings, and it will be understood that any modifications in the specific details shown and described may be made within the scope of the appended claims without departing from or exceeding the spirit of the invention.

Figure 1 is a rear view of a mounting made under our improved process- Figure 2 is a perspective view of a sheet of stock showing how the parts are cut therefrom.

Figure 3 is a perspective view of the composition member prepared for reception of the metallic member.

Figure 4 is a View of the parts united.

Figure 5is a perspective view of the completed article.

Figure 6 is a perspective view of the metallic insert.

Figure 7 is a plan View showing how a shaped temple is cut from the sheet stock.

Figure 8 is a view illustrating a further step in the construction of this form of mounting.

In the drawings, in which similar characters of reference are employed to denote corresponding partsv throughout the several views the numeral 1 designates the bridge of a mounting provided with the lens receiving frames 2 integral therewith, the whole being stamped or cut from a sheet of suitable composition material, which may be either of plain color or mottled in imitation of tortoise-shell or other similar substances. Carried by said front are our improved temples. vention illustrated in Figures 1 to 5 inclusive, the temples have been formed by using a flat sheet of-material 3, forming therein the longitudinal cuts 4, separating the same into strips substantially square in cross section, and splitting each of these strips as at 5 to form the two parts designated as A and B. The parts A and B ,'as shown in FiguresQ and 3 are then milled as at 6 to produce a longitudinally extending groove for the major portion of the length of the strip, the groove terminating short of one or enlargement 7, this enlargement being of size to receive a ball or enlargement 8 on the end of the metal temple member 9 which is adapted to be inserted and fit within the groove 6, and is provided with a butt or joint portion 10 to project exteriorly of the temple, as is shown in Figure 5.

The two parts A and B having been suitably pre'pared the'metal temple 9'is inserted wlt-hin the groove and ball receiving socket and the two parts are then firmly pressed together with an intervening coating of cement, as at 11. By referring to ce- In that form of the in- I shown in F igu ment is meant the production of adhesion between the joined surfaces, this being produced either by application of a coating of suitable material itself having adhesive properties, through the use of a material which will soften the surface of the parts to be united so that the parts themselves will form a cement firmly adhering one to the other, or by the use of a material having a combination efiect. In either event the parts are so united that the joint when completed will be practically invisible. To aid in holding the joint together, if desired, the metal member 9 may be made with projecting prongs 12, which bite into the material of the sections A and B andif desired may so project therefrom that their heads in the final article may be swaged as at 13, Figure 5; In any event, the parts having been joined, the block comprising the composition covering and metallic insert may then be milled, turned, swaged or otherwise formed into the shape of the final temple, as re 5, after which operations the joint at 11 will be entirely invisible and the article will present the appearance and have the durability of a unitary structure of all composition, together with the added desirability of the metallic insert, and being formed fromtthe same sheet material as the front in the case of all z lonite frames, can be made to exactly mate the front, or can be produced with'mottled or other desired results impossible where extruded rod type of other stock is employed.

Figures 7 and 8 illustrate another method of accomplishing the same result, in which in place of cutting straight strips from the sheet of material, the temples are blocked out in their final shape and then longitudinally split, the other operations being the same. 7

This is a division of the application filed February 23, 1922, hearing the Serial Number 538,635.

What is claimed is:

1. The process of producing a temple for. an ophthalmic mounting, consisting in cutting a temple blank from sheet material, splitting the blank into separated complementary portions, forming a metal receiving groove in each of said portions, inserting a I raeaeae metal member within the groove, uniting the two portions, and subsequently shaping the united parts into final form.

2. The process ofproducing a fitting for an ophthalmic mounting, consisting in cutting a temple blank from sheet material, splitting the blank into separated complementary portions, forming therein a metal receiving groove, inserting a metal member within the groove, closing the groove, and subsequently shaping the temple blank into final form.

3. The process of producing a temple for an ophthalmic mounting, consisting in cutting a temple blank from sheet material, splitting the blank into separated complementary portions, forming therein a metal receiving groove, inserting a metal member within the groove, closing the groove with a member of material corresponding to the first complementary portions, and subsequently shaping the temple blank into the completed article.

4. The process of forming an ophthalmic mounting, consisting in cuttin a piece of stock from sheet material, splitting the piece into separated sections, grooving the split halves to receive a metal reinforcement, and subsequently securing the split halves together about the reinforcement.

5. The process of forming an ophthalmic mounting, consisting in cutting a piece of stock from sheet material, splitting the piece into separated sections, grooving the split halves to receive a metal reinforcement, subsequently securing the split halves together about the reinforcement, and exteriorly shaping the stock after uniting of the halves thereof into final form.

6. The process of producing a temple for an ophthalmic mounting, consisting in cutting a temple blank from sheet material, splitting the blank into separated complementary portions, forming therein a metal receiving groove, inserting a metal member within the groove, closing the groove with one of the complementary portions, and sub sequently shaping the temple blank into the completed article.
